Mechanical stability and pore structures of modified grouting material in karst foundation SONG Guozhuang1, WANG Lianjun1, ZHANG Yanrong1, GUO Ying1, CAO Yuanping2 (1. Beijing Key Laboratory of Track... grouting material can be improved by the synergy effect of polymers system. The pore size of hardening cement paste reduces obviously and the pore radius distribution tends to thin with multiple high......
3D Bioplotting of Gelatin/Alginate Scaffolds for Tissue Engineering:Influence of Crosslinking Degree and Pore Architecture on Physicochemical PropertiesTing Pan1,2,3,Wenjing Song1,2,3,Xiaodong... the scaffolds with different pore architectures by deposition of gelatin/alginate hydrogels layerby-layer. The scaffolds with different crosslinking degree were obtained by post-crosslinking methods.Their......
fly ash in cement-based materials was investigated. The hydration heat of the composite cementitious materials was determined by isothermal calorimetry, and the hydration products, quantity, pore... of cement hydration, thus denser microstructure and more reasonable pore size distribution, but the hydration heat in total is reduced. It can also delay the induction period, but the accelerating......
Trans. Nonferrous Met. Soc. China 24(2014) 3509-3516 Effect of pore structures on corrosion resistance of porous Ni3Al intermetallics Liang WU1,2, Yue-hui HE2, Yao JIANG2, Yi ZENG2, Yi-feng XIAO1, Bo... rates of the porous Ni3Al intermetallics are not proportional to the true surface areas. The reason is that the pore size, pore size distribution and pore shape of the porous Ni3Al intermetallics......
The Influence of Ce(NO3)3·6H2O on the Inhibitive Effect of Ca(NO2)2 in Simulated Concrete Pore Solution冯兴国,左禹School of Materials Science and Engineering,Beijing University of Chemical Technology摘 要:The effects of cerium nitrite on corrosion behaviors of carbon steel in simulated concrete pore solutions were studied with the methods of linear......
Porosity and Pore Size Distribution Measurement of Cement/Carbon Nanofiber Composites by ~1H Low Field Nuclear Magnetic Resonance王宝民,ZHANG Yuan,MA HainanLaboratory of Building Materials, School..., porosity, pore size distribution and microstructure of CNFs reinforced cement-based composites were investigated in this paper. To achieve effective dispersion of CNFs, a method utilizing ultrasonic......
precursor in vacuum was studied and compared with that in hydrogen. The formation cause of pore channel was analyzed. The experiment results show that the binder removal rate in vacuum is higher than that in hydrogen. In vacuum, the organic compounds can be removed effectively without change of pore size and the pore morphology for the sample. After pre-sintering, some sintering necks form and the sample......
